Pressing bearing through the punch and die on the plate, strip, pipe and profile, etc. exert external force, so that plastic deformation or separation, to obtain the desired shape and size of the workpiece forming method, the resulting workpiece is a stamping.
Stamping bearing is the forming processing method of the workpiece (pressing bearing stamping part) that obtains the required shape and size by applying external force to the plate, strip, pipe and profile, etc. by the press and die, so as to produce plastic deformation or separation. Stamping and forging are plastic processing (or pressure processing), collectively known as forging. Stamped blanks are mainly hot-rolled and cold-rolled steel sheets and strips.
Among the steels in the world, 60 to 70% are plates, most of which are stamped and finished. The car's body, chassis, fuel tanks, radiators, drums of boilers, shells of containers, core steels of motors and appliances, etc. are stamped and processed. There are also a large number of stamping parts in products such as instrumentation, household appliances, bicycles, office machinery, and household utensils. Compared with castings and forgings, stamped bearings are thin, uniform, light and strong. Stamping can produce workpieces with stiffeners, ribs, undulations, or flanging that are otherwise difficult to manufacture to increase their rigidity. Due to the use of precision molds, the accuracy of the workpiece can reach micrometers, and the repeat accuracy and specification are consistent. Hole nests and bosses can be punched out. Stamping bearings are generally no longer machined, or require only a small amount of machining. The accuracy and surface condition of hot stamping parts are lower than those of cold stamping parts, but they are still better than castings and forgings, and the amount of machining is small.
Stamping is an efficient production method. Using compound molds, especially multi-position progressive molds, it is possible to complete multiple stamping processes on a single press and to achieve full-scale unwinding, leveling, punching, forming, and finishing. Automatic production. With high production efficiency, good working conditions and low production costs, it can produce hundreds of pieces per minute. Stamping is mainly classified according to process and can be divided into two major categories: separation process and forming process. The separation process is also referred to as blanking. Its purpose is to separate the stamped parts from the sheet material along a certain contour, and at the same time to ensure the quality requirements of the separation section. The purpose of the forming process is to make the sheet plastically deform without breaking the blank to produce a workpiece of a desired shape and size. In actual production, a variety of processes are often applied to one workpiece. Punching, bending, shearing, deep drawing, bulging, spinning, and straightening are several major stamping processes.
The surface and intrinsic properties of the stamping sheet material have a great influence on the quality of the stamped product. The thickness of the stamping material is required to be precise and uniform; the surface is smooth, no spots, no flaws, no scratches, no surface cracks, etc.; the yield strength is uniform and there is no obvious Directionality; High uniform elongation; Low yield ratio; Low work hardening.
Steel Threaded flange is the part for connecting pipe and pipe at pipe end. There are threads and holes on the flange, use threads and bolt to connect the pipes or other threaded pipeline accessories.
Because of its good overall performance, Flange is widely used in such basic projects as chemical engineering, construction, water supply, drainage, petroleum, light and heavy industry, freezing, sanitary, plumbing, fire protection, electricity, aerospace and shipbuilding.
